Chris, who portrays the superhero Captain America, has attended plenty of premieres for the Marvel franchise but that doesn't stop him being nervous ahead of certain public appearances, and Robert had to give him a pep talk ahead of the Los Angeles premiere on Tuesday (April 12) because he would not calm down.

Their new movie “Avengers: Age of Ultron” hits theaters on Friday (May 1) and Scarlett Johansson and Chris Evans teamed up for a fun-filled appearance on “The Ellen DeGeneres Show” on Thursday (April 30).

The interview began with just the “Her” hottie chatting with Ellen about how she’s done five films with Evans and “knows him too well,” though she didn’t know that he was planning to scare the bajeezus out of her by popping out from backstage.

Going into last night’s Super Bowl XLIX, Chris Pratt and Chris Evans made a friendly wager that involved their super hero alter egos and children’s charities.

The “Parks and Recreation” hunk was pulling for the Seattle Seahawks and told the “Captain America” stud that if the New England Patriots ended up winning he’d visit a Boston hospital dressed as Star-Lord from “Guardians of the Galaxy.” In return, if the Seahawks won, Evans promised to fly to Seattle and cheer up some sick kids as Captain America.
